Decoding test:

1. Without the optimization:
$ wasmtime --wasi threads --dir=/ ./ffmpeg -cpuflags 0 -i 265.mp4 -an -t 120 -f null - -benchmark
frame= 2880 fps= 94 q=-0.0 Lsize=N/A time=00:02:00.00 bitrate=N/A speed=3.92x

2. With the optimization:
$ wasmtime --wasi threads --dir=/ ./ffmpeg -i 265.mp4 -an -t 120 -f null - -benchmark
frame= 2880 fps=110 q=-0.0 Lsize=N/A time=00:02:00.00 bitrate=N/A speed=4.58x
